Which of the following relation is correct?(a) λLT = √(fy/fcr,b)(b) λLT = fy/fcr,b(c) λLT = (fy/fcr,b)^2(d) λLT = √(fy fcr,b)This question was addressed to me in an interview for internship.My doubt is from Design Strength of Laterally Unsupported Beams in portion Design of Beams of Design of Steel Structures |

Answer» CORRECT answer is (a) λLT = √(fy/FCR,B) Easy EXPLANATION: λLT = √(βbZpfy/Mcr) = √(fy/fcr,b), where βb= 1 for plastic and compact sections, βb= Ze/Zp for semi-compact sections, Ze = elastic section modulus, Zp = plastic section modulus, Mcris elastic critical moment, fcr,b is extreme compressive elastic BUCKLING stress. |
